[0036] See also Figure 2 , Figure 2 It is a schematic structural diagram of a first embodiment of a display panel provided in the present application.
[0037] The display panel 10 includes a liquid crystal layer 300, a first substrate 100 and a second substrate 200, wherein the first substrate 100 includes a first base substrate 110, the first base substrate 110 includes a first driving region 112 and a first welding region 111; the second substrate 200 includes a second base substrate 210, the second base substrate 210 includes a second driving region 212 and a second welding region 211; wherein the first substrate 100 and the second substrate 200 are arranged at intervals, the first driving region 112 and the second driving region 212 correspond to each other, the liquid crystal layer 300 is located between the first driving region 112 and the second driving region 212, the first welding region 111 and the second welding region 211 correspond to each other, the thickness of the first welding region 111 is less than the thickness of the first driving region 112, and / or the thickness of the second welding region 211 is less than the thickness of the second driving region 212, and the first welding region 111 and the second welding region 211 are used to form a welding track 400 to fix the first substrate 100 and the second substrate 200.
[0038] One of the first substrate 100 and the second substrate 200 is a driving substrate, and the other is a color filter substrate. For example, the first substrate 100 is a driving substrate, and the second substrate 200 is a color filter substrate; or the first substrate 100 is a color filter substrate, and the second substrate 200 is a driving substrate. The driving substrate may include a base substrate and a driving electrode layer, and the driving electrode layer is located on the base substrate. The driving electrode layer can be used to drive the liquid crystal molecules in the liquid crystal layer 300 to deflect. The color filter substrate can be used to filter light of a specific wavelength, so as to adjust the display screen of the display panel 10. For example, the color filter substrate may include a base substrate and a color filter, and the color filter is located on the base substrate. The color filter may include three color filter areas of red, green and blue. The first base substrate 110 may be made of hard materials such as glass, ceramics, sapphire, etc., so that the electrode layer can be carried by the first base substrate 110. The first base substrate 110 can be divided into a first driving region 112 and a first welding region 111. The first driving region 112 can be arranged adjacent to the first welding region 111. For example, the first driving region 112 can be located on one side of the first welding region 111, or the first welding region 111 can be annular so that the first welding region 111 is arranged around the first driving region 112. Meanwhile, the second base substrate 210 can be made of a hard material such as glass, ceramic, sapphire, etc., so that the electrode layer can be carried by the second base substrate 210. The second base substrate 210 can be divided into a second driving region 212 and a second welding region 211. The second driving region 212 can be arranged adjacent to the second welding region 211. For example, the second driving region 212 can be located on one side of the second welding region 211, or the second welding region 211 can be annular so that the second welding region 211 is arranged around the second driving region 212.
[0039] The liquid crystal layer 300 includes liquid crystal molecules, and the liquid crystal molecules can be deflected in the liquid crystal layer 300. The liquid crystal layer 300 is located between the first driving region 112 and the second driving region 212, and the electrode layer of the first driving region 112 and the electrode layer of the second driving region 212 can cooperate to drive the liquid crystal molecules in the liquid crystal layer 300 to deflect, thereby achieving the purpose of changing the display screen of the display panel 10. The first welding area 111 and the second welding area 211 may correspond to each other in the direction of the spacing between the first base substrate 110 and the second base substrate 210. When the first substrate 100 and the second substrate 200 need to be welded, the first substrate 100 and the second substrate 200 may be arranged opposite to each other and spaced apart. The spacing between the first substrate 100 and the second substrate 200 may be between 3 and 5 μm, and the first welding area 111 of the first substrate 100 and the second welding area 211 of the second substrate 200 may correspond to each other. Then, the first welding area 111 and the second welding area 211 are laser welded to form a laser welding track 400, so that the position of the first substrate 100 corresponding to the first welding area 111 and the position of the second substrate 200 corresponding to the second welding area 211 are partially melted to fill at least a portion of the gap between the first substrate 100 and the second substrate 200, so that the first substrate 100 and the second substrate 200 are welded and fixed. The welding track 400 may be formed by laser welding. Taking infrared laser welding as an example, the laser wavelength may be between 1000nm and 1100nm, and the specific laser wavelength may be 1030nm. The output power may be between 9w and 11w, and the specific wavelength may be 10w. The pulse width may be between 500 and 800, and the processing speed may be 10mm / s. The allowable GAP value may be less than 5um. Or taking a green femtosecond laser as an example, the power of the green femtosecond laser is 75w, which can be scanned by a 255mm long focal length galvanometer, the single pulse energy is 5μJ, and the welding speed is 10mm / s to 20mm / s.
[0040] In this embodiment, the thickness of the first welding area 111 can be less than the thickness of the first driving area 112. When performing welding operations, the welding energy can be alleviated by reducing the thickness of the first welding area 111, and the risk of stress in the first substrate 110 and internal tissue damage of the welding glass caused by more energy during welding can also be alleviated. The first welding area 111 can be thinned by etching so that the thickness of the first welding area 111 can be less than the thickness of the first driving area 112, wherein the etching depth can be set according to actual conditions. The etched surface of the first welding area 111 can be a surface facing the second substrate 210 and / or a surface away from the second substrate 210.
[0041] And / or the thickness of the second welding area 211 is less than the thickness of the second driving area 212.

The thickness of the second welding area 211 can be thinned by etching so that the thickness of the second welding area 211 can be less than the thickness of the second driving area 212, wherein the etching depth can be set according to actual conditions. The etched surface of the second welding area 211 can be a surface facing the first substrate 110 and / or a surface away from the first substrate 110.

In addition, the thickness of the first welding area 111 is less than the thickness of the first driving area 112, and / or the thickness of the second welding area 211 is less than the thickness of the second driving area 212. When the welding track 400 is formed in the first welding area 111 and the second welding area 211, the problem of large loss of welding energy can be alleviated, thereby improving the welding quality of the first substrate 100 and the second substrate 200, etc.
[0043] Further, the first welding region 111 is recessed toward the surface of the second welding region 211, so that the thickness of the first welding region 111 is less than the thickness of the first driving region 112; and / or, the second welding region 211 is recessed toward the surface of the first welding region 111, so that the thickness of the second welding region 211 is less than the thickness of the second driving region 212. In this embodiment, only the first welding region 111 may be thinned; or only the second welding region 211 may be thinned; or both the first welding region 111 and the second welding region 211 may be thinned. The surface of the first welding area 111 facing the second welding area 211 can be etched by etching, and / or the surface of the second welding area 211 facing the first welding area 111 can be etched by etching, so that the roughness of the etched surface can be improved by etching. When the position of the first substrate 100 corresponding to the first welding area 111 and the position of the second substrate 200 corresponding to the second welding area 211 are partially melted to fill at least part of the gap between the first substrate 100 and the second substrate 200, the bonding force of the filled material can be increased, and the fixing effect of the first substrate 100 and the second substrate 200 can be further improved.

Among them, the first electrode layer 120 can be plated on the first base substrate 110, and then the first electrode layer 120 is exposed, developed and etched through a mask plate provided with a light shielding layer to form a first substrate 100 that does not cover the first electrode layer 120 in the first welding area 111. Similarly, the second electrode layer 220 can be plated on the second base substrate 210, and then the second electrode layer 220 is exposed, developed and etched through a mask plate with a light shielding layer to form a second substrate 200 without covering the second electrode layer 220 in the second welding area 211.
[0053] Furthermore, the display panel 10 further includes a sealant 700, which is sandwiched between the first substrate 100 and the second substrate 200. The sealant 700 is disposed around the liquid crystal layer 300, and the first welding area 111 and the second welding area 211 are both disposed around the sealant 700. The sealant 700 can be disposed around the liquid crystal layer 300 and supported between the first substrate 100 and the second substrate 200, so that the liquid crystal layer 300 is sealed by the sealant 700 in cooperation with the first substrate 100 and the second substrate 200, so that the liquid crystal layer 300 is in a sealed environment, that is, in this embodiment, the sealant 700 can be supported between the first electrode layer 120 and the second electrode layer 220. The first welding area 111 and the second welding area 211 are both arranged around the frame glue 700. When the welding track 400 is formed in the first welding area 111 and the second welding area 211, the welding track 400 can be farther away from the liquid crystal layer 300 relative to the frame glue 700, so as to seal the frame glue 700 through the melted parts of the first substrate 100 and the second substrate 200 after welding.
[0054] Further, the sealant 700 may be sandwiched between the first base substrate 110 and the second base substrate 210. The sealant 700 being sandwiched between the first base substrate 110 and the second base substrate 210 can be understood as: the sealant 700 is directly in contact with the first base substrate 110 and the second base substrate 210, and there is no need to sandwich the first electrode layer 120 between the first base substrate 110 and the sealant 700, and there is no need to sandwich the second electrode layer 220 between the second base substrate 210 and the sealant 700, thereby improving the adhesion between the sealant 700 and the first base substrate 110 and the second base substrate 210, and improving the sealing effect of the sealant 700. In some other embodiments, the first electrode layer 120 may be sandwiched between the frame glue 700 and the first base substrate 110, and the second electrode layer 220 may not be sandwiched between the frame glue 700 and the second base substrate 210; or the first electrode layer 120 may not be sandwiched between the frame glue 700 and the first base substrate 110, and the second electrode layer 220 may be sandwiched between the frame glue 700 and the second base substrate 210.
[0055] In some embodiments, the thickness of the first welding region 111 is less than the thickness of the first driving region 112, and the thickness of the first welding region 111 is between four-fifths and nine-tenths of the thickness of the first driving region 112. Specifically, the thickness of the first welding region 111 may be four-fifths, five-sixths, six-sevenths, seven-eighths, eight-ninths, or nine-tenths of the thickness of the first driving region 112, etc. Exemplarily, when the thickness of the first driving region 112 is 500 μm, the thickness of the first welding region 111 ranges from 400 μm to 450 μm, and specifically, the thickness of the first welding region 111 may be 400 μm, 410 μm, 420 μm, 430 μm, 440 μm, or 450 μm.
[0056] And / or, the thickness of the second welding region 211 is less than the thickness of the second driving region 212, and the thickness of the second welding region 211 is between four-fifths and nine-tenths of the thickness of the second driving region 212. Specifically, the thickness of the second welding region 211 can be four-fifths, five-sixths, six-sevenths, seven-eighths, eight-ninths or nine-tenths of the thickness of the second driving region 212, etc. Exemplarily, when the thickness of the second driving region 212 is 500μm, the thickness of the second welding region 211 ranges from 400μm to 450μm, and specifically, the thickness of the second welding region 211 can be 400μm, 410μm, 420μm, 430μm, 440μm or 450μm.
[0057] In some embodiments, the first welding area 111 and the first driving area 112 are arranged adjacent to each other, and the distance between the edge of the first welding area 111 away from the first driving area 112 and the first welding area 111 close to the first driving area 112 is between 200 μm and 300 μm. Specifically, the distance between the edge of the first welding area 111 away from the first driving area 112 and the first welding area 111 close to the first driving area 112 is between 200 μm and 250 μm, between 250 μm and 300 μm, or between 210 μm and 300 μm. Specifically, the distance between the edge of the first welding area 111 away from the first driving area 112 and the first welding area 111 close to the first driving area 112 can be 200 μm, 210 μm, 230 μm, 250 μm, or 300 μm. The width of the welding track 400 may be between 50 μm and 100 μm, so that the width of the welding track 400 may be completely located within the first welding region 111 , thereby not affecting the normal operation of the first driving region 112 .
[0058] And / or, the second welding area 211 and the second driving area 212 are arranged adjacent to each other, and the spacing between the edge of the second welding area 211 away from the second driving area 212 and the second welding area 211 close to the second driving area 212 is between 200μm and 300μm. Specifically, the spacing between the edge of the second welding area 211 away from the second driving area 212 and the second welding area 211 close to the second driving area 212 is between 200μm and 250μm, between 250μm and 300μm, or between 210μm and 300μm. Specifically, the spacing between the edge of the second welding area 211 away from the second driving area 212 and the second welding area 211 close to the second driving area 212 can be 200μm, 210μm, 230μm, 250μm or 300μm. The width of the welding track 400 may be between 50 μm and 100 μm, so that the width of the welding track 400 may be completely located within the second welding region 211 , thereby not affecting the normal operation of the second driving region 212 .
[0059] In summary, a welding track 400 is formed in the first welding area 111 and the second welding area 211 to fix the first substrate 100 and the second substrate 200, which can improve the fixing effect of the two and enhance the anti-falling strength of the display panel 10. In addition, the thickness of the first welding area 111 is less than the thickness of the first driving area 112, and / or the thickness of the second welding area 211 is less than the thickness of the second driving area 212. When the welding track 400 is formed in the first welding area 111 and the second welding area 211, the problem of large loss of welding energy can be alleviated, thereby improving the welding quality of the first substrate 100 and the second substrate 200, etc.
